yes not even china can build 20 jf-17s a year, they have their own af to worry about.
they are also building j-10s, j-11s, and other a/c for their af i dont think they have time for 20 jf-17s.
also they have been known to cut corners to get that cheap 15 million dollar cost, its not all just labour the skin could be thinner, less rivets, cheaper canopy, cheaper electronics, etc...
so its better to build in ur own country than china which i believe will be done.
if u want proof of this

Shanghai's steel fails basic tests
Shanghais futuristic skylinethe city has more than 900 high-rises, with hundreds more under constructionis one of the most potent symbols of Chinas economic rise. But the materials undergirding all that growth might be shakier than anyone can imagine. In March, the English-language Shanghai Daily reported that fully half of the steel sold to construction companies in Shanghais wholesale markets failed basic quality tests. Nearly a quarter of the tested samples failed tension tests, meaning structures built with them would not be able to withstand earthquakes and would be more likely to decay over time.
Of the 52 batches of steel tested by the Shanghai Industrial and Commercial Administrative Bureau, 27 were too light to meet Chinas legal standards. Some batches were nearly five times lighter than the legal standard, meaning that they were less than the weight of iron, steels primary ingredient. If your steel is less than the weight of iron, thats pretty incredible, says Christopher Earls, professor of civil engineering at Cornell University. That means youre replacing the iron with something else, so what you have isnt really steel at all.
The bureau ordered construction sites using the inferior steel to halt work, but, troublingly, did not publicly reveal where it was being used. Adam Minter, a Shanghai-based journalist who blogged the story after it broke, asked, What will happen to twenty-year home mortgages taken out on Shanghai apartments which will only laststructurallyfor ten years? At some point, Im pretty sure this is going to become an issue. After the collapse of substandard schoolhouses during this years Sichuan earthquake, tremors of which were felt in Shanghai, the prospect of something similar happening to an urban high-rise isnt an issue anyone should take lightly.
and this was in skyscrapers in shanghai where 100s of thousands of people live.
